Applying the species-curve of Wade ...

Applying the species-curve of Wade and Thompson (1991) the predicted species richness of the EBP was 511 species. The total species richness was 497 species and the deviation value of actual from predicted divided according to predicted was -2.8%. The 497 species constitute 373% of the 1334 taxa known from LBL (Chester 2003) and 191% of the 2600 taxa known from Kentucky (Jone 2005)

S??renson Community Coefficient

Martin and Taylor (2002) listed 183 vascular species from seven successional old-field grassland sites within the LBL; 163 of these species were fix in this survey. When comparing the EBP flora and the flora of the seven grassland sites studied at Martin and Taylor (2002), S??renson's Community Coefficient [also known as Index of Similarity (IS)], is 942% Any pair sites may be assumed to be of the same community original if the IS is 50% (Barbour et al. 1999) The EBP flora is definitely representative of these old-field successional grassland sites.

Habitats

Seven habitats delineated in the EBP are unimpassioned Season Grassland, Warm Season Grassland (Grassland Barrens), Corral Pasture, Corral Gravel, Oak-Hickory Forest, water-gruel Pine Forest, and Wet Pond Borders (Figure 2)

Cool season grassland. The collected season grassland consists of 316 ha and encompasses the entire 80 km perimeter border, adjoins oak-hickory forest and warm season grassland, any of the Crooked Creek intermittent tributaries, and part of the asphalt-paved road (Figure 2) The asphalt road forms a one-way turn 5.0 km long and comprises 40 ha of surface area. The unconcerned season grassland is mowed each year to help direct herbaceous exotics and woody invaders and to provide palatable forage for moose and bison. The preeminent species are the exotics Festuca elatior and Lespedeza cuneata. In 1995 and 1996 these pair exotics were initially planted for erosion have charge of over much of the render free of access EBP, often intermixed with Trifolium pratense and T repen as veil crops after heavy ground clearing of oak-hickory forest and burgout pine stands.

The indifferent season grassland is characteristically give an account ofed by many native and exotic members of the Poaceae, Asteraceae, and Fabaceae. Important grasses include Andropogon virginicus, Dactylis glomerata, Panicum spp Paspalum laeve, Phleum pratense, Poa pratensis, Schizachyrium scoparium, and Tridens flavus. Characteristic composites are Ambrosia artemisiifolia, Aster dumosus, A. pilosus, Erigeron annuus, E strigosus, Eupatorium rotundifolium, Helianthus hirsutus, Solidago canadensis, s juncea, and S. nemoralis. Characteristic simple pods include Chamaecrista fasciculata, Desmodium spp Lespedeza stipulacea, L striata, Melilotus alba, Trifolium pratense, and T repen Other characteristic species include Carex hirsutella, Croton capitatus, Daucus carota, Diodia tere Lobelia puberula, Pycnanthemum pycnanthemoides, and P tenuifolium.
